How the type B through-hole chamfer pushes chips down the hole
Chips exit at the bottom instead of returning through the thread
The form B chamfer for through holes has a chip breaker at the tip of the tap – an angled cut in the cutting edges. The chip breaker directs the chip down the hole, ahead of the tap tip. The chip curls into a coil, breaks into short pieces and exits the hole on the other side of the workpiece. The threads already cut remain clean because the chip does not pass through them on its way up. The M12x1.25 tap has a reduced shank according to DIN 374: diameter 9 mm, square size 7 mm.
1
Straight flute – chips do not enter it; the flute carries lubricant to the cutting edges.
2
The chip breaker at the tip of the tap directs chips down the hole.
3
The tap rotates clockwise to cut a right-hand thread.
4
B chamfer: 3.5–5.5 incomplete threads on the entry taper.
5
The chips break into segments: individual pieces at the top of the hole, with progressively more farther down. They fall out below the workpiece.
6
Feed 1.25 mm/rev, equal to the pitch of the M12x1.25 thread.
M12x1.25 fine-thread machine tap – HSSE for automotive applications
The M12x1.25 fine thread machine tap is a specialized tool for cutting internal threads with a pitch of 1.25 mm in the popular M12 diameter widely used in the automotive industry. The 1.25 mm pitch is intermediate between the coarse M12x1.75 thread and the fine M12x1 thread, and is widely used in the automotive and motor vehicle industries for suspension and engine components. HSSE high-speed steel construction with 5% added cobalt guarantees a hardness of 65-67 HRC and optimal tool life when machining materials used in automotive applications. The tool is designed for automotive parts manufacturers and automotive service shops.
Why choose the M12x1.25 metric fine thread machine tap
- Fine thread with a 1.25 mm pitch is an automotive industry standard, widely used in wheel bolts, suspension parts, and engine components
- Increased load-bearing area of the thread of the fine thread results in approximately 40% higher tensile strength than the M12x1.75 coarse thread, with better vibration resistance
- HSSE steel with 5% cobalt guarantees a hardness of 65-67 HRC and heat resistance up to 650°C, extending cutting edge life under intensive use
- The 6H tolerance in accordance with DIN 374 ensures accurate threads and full interchangeability with fasteners used in the automotive industry
- Compatibility with ER20 holders and tapping chucks with axial compensation for CNC machining centers with synchronous tapping capability
- The recommended tap drill diameter of 10.8 mm for the M12x1.25 metric fine thread ensures optimal thread engagement with minimal tool load
The M12x1.25 machine tap is used in automotive production, automotive service shops, and wherever the standard automotive M12x1.25 pitch is required. Form B with straight flutes directs chips forward when tapping through holes. Cooling with an oil emulsion at a concentration of 6-8% is recommended to maintain optimal tool life.
